Pulsed elemental analysis with neutrons is a portable system for the detection of explosives, weighing less than 45 kg. It is based on the principle that explosives and other contraband contain various chemical elements such as H, C, N, O, etc. in qu

A neutron generator-based on-line coal analysis system is described, capable of measuring the content of the major and minor elements in coal. The system utilizes reactions produced from fast and themal neutrons, as well as from neutron activation wi

The assay of nuclear waste characterized as Remote-Handled Transuranic (RH-TRU) waste presents a formidable problem due to the waste's high neutron and γ-ray backgrounds. The differential die-away technique (DDT) that is currently employed as a meth

Remote-handled transuranic nuclear waste poses a particular challenge for assaying due to the high neutron and γ-ray background that emanate from the non-fissile, but highly radioactive material, contained within the waste. The utilization of a Radi

It has been shown that narcotics, explosives, and other contraband materials, contain various chemical elements such as H, C, N, O, P, S, and Cl in quantities and ratios that differentiate them from each other and from other innocuous substances. Neu

It has been shown that for all known explosives a strong correlation exists between their O and N concentrations. C is the third element that is also common to all explosives. A system, therefore, that would be able to identify and quantify all three

PELAN (the initials of Pulsed Elemental Analysis with Neutrons) is a device that has been developed to identify a landmine through the elemental constituents of its explosive. PELAN uses neutrons as the probing particles. The incident neutrons intera

When neutrons interact with nuclei, the resulting energy of the interaction can be released in the form of gamma rays, whose energy is characteristic of the nucleus involved in the reaction. The PELAN (Pulsed Elemental Analysis with Neutrons) system
